Good dungeon rooms are lit just enough to see the path, have one focal point (a pit, an altar, a sarcophagus) and give the player cover to move between. Deepslate and blackstone palettes with soul fire make darker moods; keep the main path at light level 8 or more so mobs only spawn where you want them.
Generated by Cyrus from a written design. Previews show a cutaway: the roof and the two front walls are hidden so you can see inside.
A deepslate catacomb with sarcophagi in alcoves, soul fire, candles, bones and cobwebs.
Main blocks: deepslate bricks, cracked deepslate bricks, deepslate tiles, polished deepslate, cobbled deepslate
Larger than 48 blocks: load the .nbt with /place template, not a structure block.
A plain stone dungeon room in a cross shape: four arms, a central vault and torch light.
Main blocks: cobblestone, stone bricks, oak planks, polished andesite, stone
Each build is one room. Cyrus does not connect rooms into a full dungeon layout here; the Cyrus mod builder can place rooms like these inside a dungeon mod for you.
A WorldEdit schematic (.schem, Sponge schematic version 3, for WorldEdit 7.3+ and FAWE) and a vanilla structure file (.nbt, for structure blocks and /place template). Both are made from the same build, block for block.
Yes, within the limits above: describe it in the build generator (for example "a dark deepslate crypt with sarcophagi in alcoves, soul fire braziers and a sunken centre") or paste a picture.
